To aZyZfwtom t 'may concern: y Be it known that'vI, LUoiENPQHAnT, a` citizen o fvFranee,` residing at Philadelphia; the'connty of Philadelphia and State of Pennsylvania, have inventednew andjnseful Improvements in Dyeing' Apparatus, n of wvhieh the following is a specification. f 1k My invention relates to` anew and useful improvement v in dyeing apparatus,` and has f for itsobjectj to so lconstruct a' device of ythis description that the. dyeing materialrnaybe thoroughly" mixed and heated andr thereafter. delivered under steam pressure `to the in terior ofrevolving cylindersfvvhich latterk serve to constantly change the position of the'goods being dyed. f A urtherobject of my inventionis to provide for the delivery ofthe dyeingvmaterial in a'finelydivided'state inthe interior ofthe A furtherobjectV of' my invention iis" to provide ineens for "controlling .the heating and' mixing of tle'dyeing 'material' prier Ato its being delvered'to the interior of the cyl-y inders, and also means for controllingithe delivery of this material Ltesad cylinders.

A still :further ohifect ofthis invention is land operationl of' dyeing apparatus described 30I in my 'nitedv States "Letter'sP'atent No.M Vipeesei, dated July 23rd, 1912. g f

In carrying out my inventioneshere em-y bodied, 1 represents a tank Which mag7 be of any desired shape or construction of proper size tocarry onthe proeessr of" dyeing, and

Within this rtank are located" any desired number of cylinders 2 here' shown' as two' inv number. Each of these'cylinders is rigidly mountedupon y'afhollovv shaft 3 which latter is perforated',asindieated at 4, and this shaft' passes through the end Walls otheftank, y

ing material poured into the kettle and the proper amount of Water added thereto through the pipe 15 by the manipulation of the valve 16 after which live steam is lprojected into the contents of the kettleY by the joint after which the proper regulation of the va-'lvele will create the desired pressure ,within the kettle to provide a motive force for driving the dyeing material through the pipes 8 so that it isonly necessary to open the stop, cocks 9v to the degree desired tov cause the delivery ofjthe proper amount of dyeing 'material tothe hollow shafts These hollow shaftsbeing perforated as before de- ,scribed will permit thedistribution of the VEdyeing y material tothe interior ofthe cylinders lin ahighly divided state thus causing it to thoroughly commingle with the con- 4 tentsA of the tank and effect an even and uniform dyeing of the goods, saidvcylinders be'- ing revolved through any suitable` means such as pulleys 'or gear wheels secured upon the projecting ends of fthe' shafts 3. 35 l The .forcing of the dyeingmaterial under steam pressure to the interior of the cylinf n-dersand the proj ectingv of the` same from the .hollow shafts ina finely divided condition I have proved by demonstration is of great advantage-in the process of dyeing, and the i factthat the vlive steamvis permitted to commingle with the dyeingmaterial and is carried by said material to the'contents of the l tank .gives an efficiency tothe vdyeing process which has heretofore not been-attained.

The outerendoffeach of the hollow shafts 3 is closed in any suitable manner, here showngas a threadedplug 23.in order that the dyeing material and steam acting therewith may not escape at this point, thus permittinga certain amount of'pressure vto be created-Withinleach of the hollowishafts so l to give force to the finely ydivided projection of said material to the tank.

" During 'the dyeing operation one end of the material which is Vin la single strip, is f placed on one of the cylinders 2, thenl that cylinder is revolved, drawingthe materialV through the dye, andl when all the material has `been wou-nd on the cylinder it is stopped.

.. Theother endof the material is now placed 'onth'e adjacent cylinder and the latter rejvolved to wind the material thereon and unwindit from the first cylinder, which is allowed to run reasonably free.

When the Amaterial has been ydrawn through the dye, 'fir'st'onto" one cylinder and then the .other in the manner described and illustrated in "my Patent No. 1,033,584, dated July 23,

1912, for a suflicient length of time to se-` curek the desired shade, it is then drawn through a wringer, folded and dried as w1ll ybe obvious.

Of course I donot Wish to be limited to the exact detailsof 'construction asherein shown, nor to they particular ,design or out. line ofthe machine, nor the arrangement of theparts relativeto each other as` these may be varied within the limits lof the appended claimswithout departingfrom 'the Spirit of my invention. f

6. A dyeing apparatus comprising a tank to contain a` dye liquor, an imperforate open end cylinder for conducting the materialto be dyed through the dye liquor, the interior of said Vcylinder communicating 'with said tank at points considerably inside of the periphery of said cylinder, a vhollow shaft journalled in the tank and on which the cylinder is mounted, that portion of said shaft within the cylinder being perforated for introducing vdye liquor under steam pressure within'the cylinder whereby it will be gradually [and thoroughly mixed with the contents of the tank, a steam tight mixing kettleon the outside of the tank and communicating with the` hollow shaft, a

"pipe leading from a sourceof water supply to ysaid kettle, a ypipe leading from a source of steam supplyV to said kettle to provide thevnecessarysteam pressure for Aforcing the contentsy of the kettle into the tank through the hollow perforated y shaft and a perforated coil within the kettle and connected to the steam pipe to cause the steam to issue in jets for agitating and lthoroughly mixing the dye liquor in said kettle.

In testimony whereof, I have hereunto affixed my signature.
